Mufp 0604 21 Z Ford Supercharger Full Kit View

Weiand has been making roots-type blowers for a long time. Now a Holley brand, the Weiand roots-type supercharger, PN 77-174-FSB-1 for the small-block Ford, is still a great unit that some say is better for low-end performance than a typical centrifugal type.
